I have been making gearstick and handbrake gaiters today. Some day I may remake the top of the trans tunnel so the holes are dead center to the gearstick etc but in the mean time I needed to find a way to mount the gaiter surrounds.
I ended up putting rivnuts into some thick card, punching through the carpet and using epoxy to glue the whole lot to the back of the carpet so I now have nuts in the carpet. (sounds like something from Kama Sutra)
Ill machine the surrounds from aluminium to finish.
Cheers
